Using Cepheids to determine the galactic abundance gradient I. The solar neighbourhood [PDF]

open access: yes, 2001
A number of studies of abundance gradients in the galactic disk have been performed in recent years. The results obtained are rather disparate: from no detectable gradient to a rather significant slope of about -0.1 dex kpc -1. The present study concerns

Evaluation of research publications and publication channels in astronomy and astrophysics

open access: yesEPJ Web of Conferences, 2018
The astronomy community usually turns to the Astrophysics Data System for bibliometrics. When the context is cross-disciplinary, commercial products like Web of Science and Scopus are used along with related analytics tools instead. The results are often

The purpose of astronomy [PDF]

open access: yesVistas Astron. 39 (1995) 315, 1995
This is a presentation of the purpose of astronomy in the context of modern society. After exposing two misconceptions about astronomy, I detail its role in five domains, certified knowledge, incorporated abilities, innovations, collective goods, and popular science; with each domain is associated an institution, an incentive, and a method of ...

Analytical Constraints on the Radius and Bulk Lorentz Factor in the Lepto-Hadronic One-Zone Model of BL Lacs

open access: yesUniverse, 2023
In this work, we study the parameter space of neutrino-emitting BL Lacs under the framework of the one-zone lepto-hadronic model. We show that constraints on the model come from various aspects of observations such as the variability timescale of blazar ...

Dark Matter in Modern Cosmology

open access: yes, 2010
The presence of Dark Matter (DM) is required in the universe regulated by the standard general relativistic theory of gravitation. The nature of DM is however still elusive to any experimental search.

The new worlds observer: The astrophysics strategic mission concept study

open access: yesEPJ Web of Conferences, 2011
We present some results of the Astrophysics Strategic Mission Concept Study for the New Worlds Observer (NWO). We show that the use of starshades is the most effective and affordable path to mapping and understanding our neighboring planetary systems, to
